FUNCTIONS
1. FREQUENCY CONTROL
1) AC current peak control
Cooling mode Heating mode
17.6A 18.4A
2) Prevention control of outdoor heat exchanger overheating If the temperature of the outdoor heat exchanger exceeds the overheating prevention line 1or 2 during cooling, the operating
frequency is lowered by approximately 5 to 15Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds or approximately 15Hz once every 120 seconds. If the frequency is lowered to minimum frequency without the temperature of the outdoor heat exchanger decreasing and this condition lasts for 1 minute, the compressor will be stopped.
Overheating Prevention line 1 129.2°F (54°C) Lower 5Hz once every 60 seconds Overheating Prevention line 2 134.6°F (57°C) Lower 15Hz once every 120 seconds
3) Prevention control of compressor overheating If the temperature of the compressor exceeds approximately 226.4°F (108°C), the operating frequency is lowered
approximately 5Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds. When the compressor temperature drops below approximately 226.4°F (108°C), the frequency is raised approximately 5Hz once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature of the compressor decreasing, and this condition lasts for 1 minute, the compressor will be stopped.
4) Prevention control of indoor heat exchanger overheating Two minutes after room several decrease If the temperature of any of indoor heat exchangers exceeds the overheating prevention
line 1 or 2 during heating, the operating frequency is lowered to minimum frequency. When the temperature of all of indoor heat exchangers go below [the overheating prevention line 1 -45.5 60 seconds, and normal operation is restored. If the condition that the frequency is minimum lasts for 2 minutes, the compressor will be stopped.
<When normal >
If the temperature of any of indoor heat exchangers exceeds the over­heating prevention line 1 or 2 during heating, the operating frequency is lowered by approximately 5 to 15Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds or approxi­mately 15Hz once every 90 seconds. When the temperature of all of indoor heat exchangers go below [the overheating prevention line 1
-45.5
°
F(-7.5
°C)], the frequency is raised by approximately 5Hz once every 60 seconds, and normal operation is restored. If the condition that the frequency is minimum lasts for 2 minutes, the compressor will be stopped.
2. OVER CURRENT PROTECTION
DC over current detection, AC over current detection To protect against over current due to sudden change in load, the
compressor is stopped if 25A DC is exceeded in the DC section. If the set value of AC current is exceeded in the AC section, the compressor is stopped. 90 seconds after the compressor has been stopped, another starting try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is stopped. DC over current is detected by the power module. AC over current is detected by CT1, on the outdoor PWB.

3. COMPRESSOR PROTECTION CONTROL
If the temperature of the compressor exceeds 235.4°F (113°C), the compressor is stopped. In this case, the outdoor fan is
not stopped until the temperature of compressor drops below 210.2°F (99°C). In 90 seconds after the compressor is stopped, if the temperature is below 194°F (90°C), another starting try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is stopped.
4. POWER TRANSISTOR MODULE PROTECTION
If the temperature of the chips in the power transistor module exceeds 212°F (100°C), the compressor is stopped. In this
case, the outdoor fan is not stopped until the temperature of power module drops below 185°F (85°C). In 90 seconds after the compressor is stopped, if the temperature is below 185°F (85°C), another starting try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is
stopped.
